If people's minds were so weak to give into intrusive thoughts, I'd have committed suicide maybe a year or two into my intrusive thoughts.

As I said before: what happens in this comic is unrealistic. People who struggle with undiagnosed depression can (and do), survive for years despite thinking about killing themselves every day, every hour, for years.

I know. I went through this. You don't just "give up" randomly (and emperically speaking: people at this stage don't often commit suicide IIRC), though the feeling does wear you down and make you anxious over time. There's "stages" of depression and suicide, and if its just intrusive thoughts that are messing with you every waking hour of the day, you're not quite at the depths of suicide quite yet. (Yes, it gets worse than just thoughts. Although you probably should seek help if you are at this stage).

As I've said in the other comment: real life is far worse than what's presented here. Those who HAVE gone through this can't relate to it, because the people who jump into the holes were so far less weak-willed than any real world person.

There are "stages" after intrusive and chronic long-term thoughts... when your brain starts to actively plan to do something harmful. An entire tier of thoughts and planning that goes far deeper than the horrors that was in the holes story.

The horrors of living with suicidal depression for months, years, is knowing what lies on the other side of the hole, but deciding to jump in anyway. Real world is far worse than what happens in the hole story. I know I'm going to die if I give into the thoughts. Its not some mystery or drive to explore or something that's causing my brain to think those thoughts. (And honestly, if it were "just" a feeling to explore or figure out the mystery, it's far less horrific).
